She responded:[12]

I believe that all women should always be entitled to our own opinions and we should have the most autonomy on whatever decision that we have towards our bodies because as women, we are a tower of strength, a pillar of hope, and a champion of purpose. We should always believe that all our choices should always come right into our hands.

She responded:[22]

“I would definitely say that our generation, although misconstrued as very ardent, …we use our voice for a reason, and that is to always speak up for the things that we know are right, and for the things that we know that we deserve. That is why we are very ardent about it.”
